Sarens Transports and Installs Twelve 2.65MW Wind Turbines in Vietnam

January 2019:Sarens was commissioned by
Siemens Gamesa Renewable Energy to transport and install twelve
G114-2.6MW wind turbine generators at the Dam Nai Wind Farm -II in
Vietnam. With the second phase added, this wind farm is now the
largest of its kind in the Southeast Asian country. The second
phase, having a total investment of US$ 60 million, has an average
generation of 110 million kWh per year.

Strong winds kick up in this region from around October before
which the plant had to be operational. The deadline between the
contract's execution and the commissioning of the wind farm was
very tight. Our teams were simultaneously facing a challenge of
transport option available only during the night for a few hours.
To meet the deadline our crew decided to work in two shifts
installing two WTG/week.

Sarens deployed the following equipment:

For Transportation:

Extendable trailers

Low bed trailer

Hydraulic conventional trailers

For Erection:

Two 600T Crawler crane

100T Crawler crane

80T Crawler crane

500T hydraulic crane

120T Rough terrain crane

60T Rough terrain crane

32 axle lines of SPMT

Two PPU, 3x5T telehandler, flat bed trailer

The equipment was transported by trailers from the storage yard
in Vietnam in five days. Three flatbed trailers, 32 axle-lines of
SPMT and 2 PPU at site were deployed for relocation. The equipment
was carefully and safely assembled in five days as the hardstand
was narrow and unlevelled.

All the tower sections, hub, nacelle, and blades were
transported during night due to transport restrictions through
public places. Once moved to site, three tower sections, hub,
nacelle, three blades each for the twelve WTGs were lifted and
installed at a rate of thirty hours/WTG.

Our teams were challenged by heavy rain and strong wind due to
which they had to stop the operation in between and then begin
installation again to ensure safety. Despite the challenges the
installation was successfully competed at a rate of 2WTGs/week.
Sarens was awarded and certified for its outstanding performance
and lasting contribution of 350,000 safe man-hours without fatality
at the Dam Nai wind farm project.
